Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33551928, here are decompositions:

19 + 33551909 = 33551928
61 + 33551867 = 33551928
79 + 33551849 = 33551928
89 + 33551839 = 33551928
127 + 33551801 = 33551928
131 + 33551797 = 33551928
191 + 33551737 = 33551928
197 + 33551731 = 33551928

Showing the first eight; more decompositions exist.
